Yes it's a cabbage and it is my latest painting. I have been working on this at Gallery 150 in Leamington Spa. I still have a little more to do with it, it doesn't have any shaded bits yet or highlights plus I have to tidy up some of the rough edges. I have only used 2 colours and they are sap green and alkyd white (oh a little bit of raw umber on that small amount of background you can see).
Below is a photograph that I took today, it is the hand of a former squadie, I think it speaks volumes but you might not agree.
